An Annual General Meeting (AGM) is a formal, legally required yearly gathering of a company's shareholders and board of directors. It is the primary event where shareholders exercise their voting rights, review the company's financial performance, and hold management accountable. Public companies in the United States and most other countries are legally required to hold an AGM. The Securities and Exchange Commission requires all public companies to make their annual meeting materials available online.
Think of an AGM as the one day each year when the people who own the company get to sit across the table from the people who run it.
The agenda is structured and predictable. Every AGM covers a core set of business items, though additional topics can be added by the board or shareholders.
Shareholders who cannot physically attend can vote by proxy. A proxy authorizes another party to vote on their behalf. Most large public companies distribute proxy statements well before the AGM, detailing every item that will be put to a vote. Institutional investors like pension funds and mutual funds routinely cast proxy votes across hundreds of companies they hold.
The proxy system is where real power is exercised in most AGMs. Individual shareholders who show up in person represent a small fraction of total voting power. The outcome of most votes is determined by institutional proxy submissions submitted days before the event.
When a company is in financial trouble or its stock has performed poorly, the AGM becomes a flashpoint. Large institutional shareholders use the meeting to challenge management decisions, demand executive accountability, or push activist proposals. Warren Buffett's Berkshire Hathaway AGM in Omaha, Nebraska, has drawn over 10,000 attendees annually and is known colloquially as "Woodstock for Capitalists," representing the positive extreme.
Activist investor campaigns frequently culminate at AGMs. If an activist has accumulated enough shares, they can nominate directors, put forward shareholder resolutions, and publicly pressure the board to change strategy, all at the annual meeting.
Notice of an AGM must be provided in advance, typically 21 days minimum in most jurisdictions. The notice must specify the meeting date, location, and agenda. A quorum, the minimum number of shareholders or share votes required to make the meeting valid, must be present or represented by proxy before business can proceed. If quorum is not met, the meeting must be adjourned and rescheduled.
In the United Kingdom, the Companies Act 2006 made AGMs optional for private companies from October 2007 onward. Only public companies are required to hold them. In Singapore, private companies can also opt out of holding AGMs. Different jurisdictions apply different requirements, but the core principle of annual accountability to shareholders holds broadly across major economies.
